Sure—I don’t think “systematic change” is a well-defined category. The relevant distinction is “easy to analyze” vs “hard to analyze”. But in the post you’ve basically just stipulated that your example is easy to analyze, and I think that’s doing most of the work.
So I don’t think we should conclude that “systematic changes look much more effective”—as you say, we should look at them case by case.
